INFICON Front Load Single crystal sensors offer proven reliability and durability and have the best thermal stability of any sensor head on the market. The front load design allows for easy insertion of the crystal holder in applications lacking sufficient room for side insertion. Assembled mechanically rather than soldered, parts can be replaced conveniently in the field, if necessary. Sensors can be ordered individually or in a sensor / feedthrough combination that can be either welded or assembled with compression fittings. Sensor Configurations Two sensor configurations are offered: The standard version and the right angle (compact) version. The standard version is designed for installation from the side or bottom of the chamber having the cooling tubes parallel to the crystal face. The right angle version is designed for installation through the top of the vacuum system having the water cooling tubes perpendicular to the crystal face. Optionally, sensors can be ordered with a pneumatically driven crystal shutter to protect the crystal during source warm up, when not used during deposition of an alternate material, or to extend crystal life when used with RateWatcher. The shutter is designed to flip down allowing easy crystal replacement. The exposed crystal electrode is fully grounded to effectively eliminate problems due to RF interference. Feedthroughs INFICON offers two types of feedthroughs, either a 1 inch bolt feedthrough or a 2¾ inch (CF40) ConFlat flange feedthrough. KF40 feedthroughs are available on request. Feedthrough Connection s can be ordered in combination with a feedthrough. The sensor / feedthrough connection can be either welded or made with compression fittings. Compression fittings allow for easy adjustability without the need for brazing or welding. The feedthrough can be moved along the length of the tubes allowing the length inside the vacuum systems to be adjusted over a range of 20.3 71.1 cm (8 28 in.) for E length sensors. Once the desired length is determined, the compression fittings allow for a finger tight tube seal. Alternately, a welded connection may be chosen. ADVANTAGES Front load crystal holder Easy installation Available with: CF40 feedthrough 2.54 cm (1 in.) bolt feedthrough Adjustable length if ordered with compression fittings Sensor / feedthrough combinations available welded to customer specified lengths. No brazing required if ordered with compression fittings or welded to feedthrough

Other lengths will be considered a special order and will be subject to additional cost and lead time A B E SL NOTE 1: Feedthrough configuration varies depending on options selected (Front Load or Cool Drawer, with or without shutter, type of feedthrough, etc.). Example: SL-A0E37 uses feedthrough PN 002-042 while SL-A1E37 uses feedthrough PN 750-030-G1. NOTE 2: Sensor lengths are measured from center of the crystal to the vacuum side (sealing surface) of the feedthrough. Once a welded sensor order is confirmed, it cannot be cancelled. NOTE 3: Front Load Sensors ordered with shutters and 1 in. bolt style feedthrough can only be welded (compression fittings not available). NOTE 4: Front Load Sensors ordered with a CF40 feedthrough and a shutter cannot be welded due to dimensional limits of the CF40. NOTE 5: Front Load sensors welded to lengths between 28 34 in. will include a 36 in. in-vacuum cable. Sensors welded to lengths between 34 39 in. will include a 48 in. in-vacuum cable. The following combinations are not available: (see notes 3 and 4): SL-A1E38, SL-B1E38, SL-A1E47, and SL-B1E47 Examples of non-valid part numbers include all options with no feedthrough connection or compression fittings and a welded sensor length; for example, SL-A0E48-20, SL-B1E40-20, etc. Sensor Substrate In-vacuum cable Feedthrough Source Shutter Controller or Monitor 2 Short 6 in.
